.N. Y., A GORPORA'JJIONl,0F` DELA-i WINDOW Fns'rnNnn.

Application filed April 11,

Reference is had to the accompanying drawings which illustrate the preferred form of the invention, though it is to be understood that the invention not limited to the exact details of construction shown and described, it is obvious that various modifications thereof Within the scope of the claims Will occur to persons skilled in the art.

In said drawings:

Fig. l is a fragmentary view of a portion of a bus body, showing the invention applied thereto;

Fig. Q is a sectional view on the line 2--2, Fig. l;

Fig. 3 is a sectional view on the line 8-3, Fig. 4, and

Fig. 4 is a side elevation of the device.

The primary object of this invention is to provide a fastener for Windows or the like which will eliminate to a great extent, 1f not entirely, excessive vibration, and the rattle incident thereto, of suoli Window.

Another object of this invention is to provide a window fastener which Will retain the window in either open or closed position, as desired, in such manner that vibration thereof is reduced to a minimum.

A still further object is to provide a Window fastener which will function both as a Windowv opener` and a Window closer, as the case may be.

Other ob'ects and advantages of the invention Will be apparent from the following description, taken in conjunction With the accompanying drawings, in which the reference character A designates a portion of a passenger vehicle, such, for example, as a motor bus or the like, which is provided with the usual Windows B. It is customary in buses and other passenger vehicles in use at the present time to provide other Windows for the benefit of passengers Who are required to stand, and also for ventilating purposes, and the drawings disclose a vehicle of this character in which are shown relatively small Windows C each comprising a frame l and a glass 2, said windows being positioned in openings delined by the bus body. The Windows C, as Clearly shown in Fig. l, are hingcdly connected at the lower end thereof, as shown at 3, to

the bus body in orderthat they may swing' downwardly for Ventilating purposes. S0 fai', the'construction describedis usual in passenger vehicles. The present invention re-y lates to a means for, fastening the Windows C, and to'that'end there is shown more clearly in Figures 3 and 4 the ydevice of the present invention.`

As shown, there is provided a bracket 4 having near one end thereof an opening yin Which 670 is received a pivot rod 5 Whichinay be fiXedly secured Within 'said'ibracket 4, if desired, `or Whichmay havea revoluble `fit in saidopen-l ing. One endof said pivot rod 5 is extend'- ed beyond the bracket 4and'is provided With an annular groovek or recess 6."

Pivotally connected to the entended'end of the, pivot rod 5 is ai tubular housing 7 Which is plugged at oncend, as shown' at 8, the pivot rod 5 passing through said plug' 8, as shown'. A. pin/9 is mounted inthe plug 8 and housing 7 Lat right anglesto the pivot rod 5 and engages ythe recessr 6 thereby re*-M taining the housing' 7 on pivot 5 and allowing the saine to oscillate thereon. The housing 7 normally depends fromthe pivot rod 5 andis provided with aplunger l0 having an enlarged rear end ll, said plunger working Within the' housing Tand against the tension of a coinpression spring 19., one end of which bears against the plug y8 and the oppositeeud of which has a bearing against the' rearend `of the enlarged portion 1l of the plunger 10. y 1

The free end of the housing 7 is slightly reducedv as shown( at 13 and Within this reduced end isabushing 14, the rear end ofL which serves asalimiting stop 'for the en? larged portion'll` ofthe plungerlO. The free end of the lplunger l0 is threaded into an interiorly threaded sleeve- 15 formed with a pivot rod 17 avhich extends into a bracket 19 secured to the Window frame l, and a nut 'lo is provided for retaining the plunger l() in any desired position whereby the plunger l() may be adjusted to compensate for. loss of tension in the spring l2.

ln use,l the bracket 4 is secured to the Window jamb Q0 as shown in Fig. 2, and, as betere mentioned, the bracket 19 is connected to the Window frame 1. F ig. 2 discloses, in full lines, the Window C in its closed position With the Window fastener associated therewith, and from an inspection of this ligure, it Will be obvious to those skilled in the art that the spring 12 is under extreme compression,

thereby retaining theWindoW C in closed position With the danger of vibration reduced to a minimum due to the constant pressure exerted on the WindoW't-hrough the medium of the spring and the bracket 19. When it is desired to open this Window for Ventilating purposes all that is necessary is to pull the Window from its closed position to the open position shovvn in dotted lines in Fig. 2, hand grasps 21 being provided for this purpose.

D uringthe operation of opening the Window,

, it will beapparent that the latter Will swing rotatable in the sleeve member to adjust the on its hinge 3'in an arc and when the pivot rod 17 has passed the center yindicated by the pivot 5, the plunger 10 will be extended With the spring 12 exerting its compression through'the bracket 19 onto the Window C, thus reducing vibration of the Window C in its open position, to a minimum.

lVhat is claimedis:

1. A Window fastener comprising a bracket secured to a Window jamb, a pivot pin carried by the bracket, a housing supported by the pin, a spring in said housing, a. plunger Working in the housing and normally urged to extended Yposition by said spring, a bracket secured to the Window frame, a pin pivotally mounted in said second named bracket, a sleeve carried by4 the pin andV adjustably receiving the endfof the plunger, and a lock nut mounted on the plunger end and engaging the sleeve to retain the plunger in desired adjusted spring.

2. A Window fastener comprising a bracket secured to a Window jamb, a otally connected to said `bracket, said housing, a plunger Working in the hous-y ing and urged to extended position by said spring, saidy plunger having a threaded end, a bracket secured to a Win-dow frame, a sleeve member pivotally secured to the second named Vbracket and in Which the threaded end of the plunger is received, the plunger being position thereof in the housing against the tension of the spring, and means for securing the plungerinadjusted position. y

- In Witness whereof I have hereunto set my hand.
